Exact lookup

1. lookupDef :: Eq k => v -> k -> AssocList k v -> v

   hxt	Data.AssocList

   lookup with default value

2. lookupNode :: Ord a => a -> NodeMap a -> Maybe Node

   fgl	Data.Graph.Inductive.NodeMap

   Lookup for the node in the map.

3. lookupDefault :: StaticMap t => Val t -> Key t -> t -> Val t

   relude	Relude.Extra.Map

   Return the value to which the specified key is mapped, or the default value if this map contains no mapping for the key.

   >>> let myHashMap = HashMap.fromList [('a', "xxx"), ('b', "yyy")]
   
   >>> lookupDefault "zzz" 'b' myHashMap
   "yyy"
   

   >>> lookupDefault "zzz" 'c' myHashMap
   "zzz"
